IMPROVEMENT IN ATTACHMENTS FOR FLOWS.

Specification forming part of Letters Patent No. EGLHQ E 0, dated April20, 1875; application led October 27, 1874.

To all whom it may concern:

Be it known that I, ELIsHA N. YARDLEY, of Tonganoxie, Leavenworthcounty, Kansas7 have invented a new and useful Improvement in Attachmentfor Plows, of which the followin g is a specification:

The invention relates to attachments forl plows. Its object is toprovide an implement which may be readily attached to plows ot' allconstructions, and which e'ectually turns down and holds in such mannerthat it is covered by the action of the plow-share whatever vegetationis between the point of the share and the furrow next thereto.

ln the accompanying drawings, Figure l is a perspective view ot' adevice embodying the invention. Fig. 2 is a detached view of a form ofthe attachment.

Agis the beam of the plow, to which, near its forward extremity, issecured the metallic plate B by means of the clevis C, and otherwise, aswill hereinafter appear. In the plate B an aperture is cut which iscontinued through the plow-beam, through which is passed the upperextremity of the attachment l), which occupies a horizontal positionwhen the device is attached; or a box, E, may be fastened to the lowerside or" the plow-beam, as in the present instance. The extremity ot thepart D extends beyond the side ot' the plow-beam or box removed from theplate B, and is provided with a thread to carry a nut by which theattachment is securely made fast.

In Fig. 1 of the drawings the shape of the device is shown withdistinctness. It consists of a single rod of iron bent and curved so asto produce the lines and angles substantially as shown.

The invention, as embodied in the present device, may be described asbeginning at the part D, above mentioned, next to which, and at about aright angle thereto, occupying nearly a horizontal posit-ion parallel tothe plow-beam, is the drag-bar H, which is bent at I substantially atright angles to the dragbar H, and depending to a point nea-r theplow-share, from which point extends forward somewhat in advance of thepoint of the plowshare, from whence it curves backward, forming a pointat K, and terminating in the loop L, which projects forward in a planeabout parallel to the drag-bar H, and in which is placed the shield l,that may be of wood, the object of which is to prevent the loop frombecoming clogged with vegetation.

The length of the point K should be such that when the device isattached the loop L will occupy the furrow next to that which is beingmade; and the other parts should be adapted to the height and length ofthe plow to which they are to be applied.

In the present instance I have applied a spring, M, which may beadvantageously used when the vegetation is exceptionally heavy, butwhich may be omitted without destroying or impairing the invention.

It is entirely obvious that the construction I have described is not theonly one which may be effectively employed, and I do not confine myselfto it. Thus all the parts of the attachment, (including the plates,clevis, pivot D, drag-bar H, and spring M,) except the point K and loopL, may be omitted, and othertexpedieuts resorted to which will serve tohold the said essential fea-tures in place.

Any proper means for holding the sweep and loop in the position shownmay be successfully made use of without impairing the prime object ofthe invention.

It is, however, important that the said essential parts be so arrangedas to have a yielding pressure to accommodate them to the inequalitiesof the surface of the ground, and other incidents.

rIhe operation of the device is as follows: Having applied it to theplow, the plowing is proceeded with. rllhe point of the share enteringthe earth, the forward extremity of the point K, dividing thevegetation, carries it toward the loop L, at the same time bending itdown and coacting with the plow-share to roll or turn it in line withthe sod which is borne by the share over the roll of vegetation,covering it completely.

Thus the vegetation is so directed that it is virtually Wrapped in thesod Without interfer- In testimony that I claim the foregoing im ingwith the ordinary functions of the plow, provement in attachments forplows, as above and thus eft'ectually turned under. described, I havehereunto set my hand and What I claim as my invention, and desire seal.

to secure by Letters Patent, is ELISHA NICHOLAS YARDLEY- LL S-l The bentdrag-bar H, pivoted to the plow- Witnesses:
